Neurologic complications of 2009 influenza A (H1N1)

Abstract
Rare cases of influenza-associated neurologic complications have been reported for decades. “Acute encephalopathy” was reported in association with the devastating 1918 “Spanish” influenza A (H1N1) pandemic.2 Recognition of the association of salicylate ingestion in children with influenza and development of Reye syndrome has led to preventive efforts and a dramatic decrease in this complication.3
